Waymo co-CEO Dmitri Dolgov laid out the clearest technical case yet for why cameras alone can’t take a self-driving system to full autonomy, arguing that “weak sensing” hits a safety ceiling long before it reaches superhuman performance. He never said the word Tesla. But camera-only is Tesla’s entire bet, and this was a direct shot at it. Dolgov made the comments in a talk at Y Combinator’s Startup School, walking through the lessons Waymo has learned building its driver over close to two decades. He put the sensor question on the table plainly: “there’s been a long-standing debate about what kind of sensors do you actually need for autonomous driving.” His answer draws the line that camera-only advocates tend to skip right past. “Humans of course can drive with just eyes, so there’s that proof of existence,” he said. “If the goal were to just approximately match human performance or to build an assist product, that’s a very reasonable way to go.” Then the catch. If you’re targeting full autonomy and strongly superhuman performance, he said, “you find that weak sensing just leads to a safety curve that flattens out way too early.” That’s the whole argument in a couple of sentences. Cameras can match a human. They can power a driver-assist product. Dolgov’s point is that they top out below the bar a car has to clear to drive with nobody behind the wheel. Unless you do it for demonstration purposes in a geo-fenced area with limited speed and low availability to limit danger through less mileage. Waymo uses three sensing types, and Dolgov spent real time on why. Cameras give you high resolution and color, but they’re passive, and they degrade in darkness and glare. Lidar directly measures the 3D structure of the world. Radar punches through fog, rain, and snow, and reads velocity directly with Doppler. Lidar and radar are active sensors, so they see just as well in pitch darkness or straight into a blinding sunset.
